I ordered a core ECM and got the performance tune installed with a bonus EGR delete. What a difference this tune makes. My DTS leaves from the dig harder and accelerates faster. I dragged a Lexus, Mercedes and BMW on the way home after getting this installed. Definitely going to need more rubber to harness this extra power. I spoke with Jake directly via email and he definitely hooked me up with a killer tune. 10/10 recommend this for any Northstar V8
